Nios Stratix

Hi,

I'm trying to use a NIOS Kit Eval Board (Stratix10).

I would like to do a small application :
=> incr a counter value in FPGA (VHDH code)
=> convert this value Hex to Dec in FPGA (C code)
=> use NIOS (UART) to display this Dec value in IHM (SOPC, Hyperterm, ...)

I'm searching samples. Could you help me ?.
Thanks in advance.

    Benoit.
